Dear all i have a quarry regarding weld overlay of brass on on carbon steel.
I did the weld overlay of E-CuAl A2 electrode on carbon steel forging by process SMAW. As the electrode used was 3.15mm , all the parameters were set i.e current was 110Amp & voltage was 22, travel speed was normal.
After welding i faced a problem that i found huge porosity in the weld bead after grind. I tried all the efforts to remove the porosity but it fails to find the root cause.
So this is request to all of you kindly suggest me for smooth and fine weld.
